Hi all,
I'm working on a autocomplete/autosuggest box to search for a member in my mssql database ( >9000 records ) and succeed doing so.
My only problem is load time get up to almost 10 sec every time the page loads.
Basically,
- I opened db and saved the table to GetRows().
- Run the array to save Names and IDs into 2 different strings with comma deliminator.
- Assigned the 2 strings to JScript variables.
- JScript will then autocomplete searching for match typing name.
- When name was clicked, the Onclick will take me to the next page with the right ID# that has the same in the JScript For Loop.

I'm hoping that there is/are better way to do this and here is my code, briefly:
Code:
<%
mySQL = "SELECT memberName, id " _
	  & "FROM tblMembers " _
	  & "ORDER BY memberName" 
set rs = objConn.Execute(mySQL)
If NOT rs.eof then
	arrContacts = rs.GetRows()
End If
call closeRS(rs)

If isArray(arrContacts) then
	For iCust = 0 to uBound(arrContacts,2)
		if len(trim(arrContacts(0,iCust)))>0 then
			mNames = mNames & ", """ & REPLACE(arrContacts(0,iCust),"""", "'") & " (" & Trim(arrContacts(1,iCust)) & ")" & """"
			custIDs = custIDs & ", """ & arrContacts(2,iCust) & """"
		end if
	Next
	custNames = Mid(custNames,3)
	custIDs = MID(custIDs,3)
Else
	custNames = ""
	custIDs = ""
End If
%>
<script type="text/javascript">

function handleKeyUp(maxNumToShow)
{
    var selectObj, textObj, functionListLength;

			//selectObj[numShown] = new Option(functionlist[i],i+100);
            numShown++;
        } else {
			document.forms[0].functionselect.style.display = "";

        // Stop when the number to show is reached
        if(numShown == maxNumToShow)
        {
            break;
        }

    if(selectObj.length == 1)
    {
        selectObj.options[0].selected = true;

    parent.location.href = 
	"/edit.asp?id="+selectedValue;

}

Most of tutorials out there only get me to set the Name to input text field without the ID#, so keeping this structure is preferable.

Thank you.
 
Have you run the select against the db itself, or on a test page to ensure that your select is not the problem?

You've got questions and source code. We want both!
 
The SELECT is against the db itself, no problem there. I understand there are many different ways to select from db and utilizing an array. From what I have had, can you tell me the faster or optimum way to run 9000+ records.

I understand this is ASP forum so let just focus into the SELECT part. (however, if anyone with jscript knowledge is welcome as well)
 
90k records isn't a lot to spin through with a select, but it will bring a drop down to it's knees.

You may want to wait for the first character and then do an async call to get the result set. Limiting to 10-20 to ease processing.
